HV623 - 32-Channel 128-Level Amplitude Gray-Shade Display Column Driver
The HV623 is a 32-channel driver IC for gray shade display use.
It is designed to produce varying output voltages between 3 and 80 volts.
This amplitude modulation at the output is facilitated by an external ramp voltage VR.
See Theory of Operation for detailed explanation.
